I have had a full day at work, and after coming home had to do some weekend shopping first and next my own household chores, after that I did about an hour of studying from my GENKI book. Then I decided for some fun time, so I went to YOUTUBE to seek out one of the Hatsune Miku shows, the one I choose lasted nearly two hours.I already knew the word ココロ because it is a topic in many of the vocaloids songs. It's actually hard to miss. This time, as Kagamine Rin was singing the song by that name, I noticed the word きせき repeated several times; and when the show over I decided to find out what it means. That wasn't difficult at all.That's how I spend my Friday night.

And then, just before my bedtime, I visited this forum once more and decided to respond to your last post with my newly-found word. I might have been a little bit too impulsive on that: I complete forgot about the rules of this game. I'll try to do better next time.
